“As a former Ashtanga practitioner I had to unlearn a lot and relearn a new pain free way of yoga during my teacher training with Aaron. The way he integrates his knowledge of Applied Yoga Anatomy and Muscle Activation™ is a mindful and safe way to practice yoga. In a short period of time my shoulder pain got less and less and I felt more strength throughout my body.

Now I look at some poses in yoga in a different light and have a much greater understanding of their impact on the body."

Blue Osa yoga testimonial for yoga teacher training


"I’m grateful for having clarity and overwhelming sense of peace I am taking away from some of the challenges I was working through during my time spent at Blue Osa.

I wanted to let you know I’ve felt a particular appreciation for your capacity as a space-holder and witness, and find it admirable how you remained seemingly unphased by what could quickly be triggering actions from myself and others."

~Varun - YTT Graduate, 2017



"My time at Blue Osa was among the most incredible journeys I have ever undertaken, from both an amazing travel experience to probably the most substantial period of personal growth I have ever undertaken. From the friends and community I gained, to the awe inspiring yoga practices.

I am still in awe of everything I experienced in those two weeks. The wisdom you imparted upon us was simply life changing. I have never been exposed to yoga as profound as this experience. You are an incredible person and I thank you for opening the door to a whole new world to me."

"Being at Blue Osa woke me up.  I am finally consistently meditating for the first time in my life and I feel subtle yet powerful shifts in my outlook.

I am finally consistently meditating for the first time in my life and I feel subtle yet powerful shifts in my outlook. I see a difference in the way I react to things. I finally have some autonomy over my emotions.I see a difference in the way I react to things.

You had such a big impact on me and I've felt compelled to write you this to you."

"This YTT at Blue Osa blew my mind, and really open my eyes to the possibilities of yoga.

Aaron is like a bright guiding light, he has such depth of knowledge and experience of these practices and traditions. I feel like I'm able to make so much more progress under his guidance.  A big win for me is my learning to speak with such COMPASSION, KNOWLEDGE, and CONFIDENCE.

I highly recommend this yoga teacher training at Blue Osa with Yogi Aaron to anyone interested in doing one! Regardless of whether you want to teach yoga or not, it’ll be greatly beneficial to your life!"

"I am so grateful for Yogi Aaron! I am now living a pain-free life. My yoga teacher training experience was magical and transformational. The training exceeded my expectations. This training guides us in the authentic yoga based in the Himalayan Tradition, and about stability of the body and mind through innovations like AYAMA (Applied Yoga Anatomy and Muscle Activation created by Yogi Aaron)!

I enjoyed learning how I can assist students with improving their range of motion through simple, yet incredibly effective exercises because we got the opportunity to put it to the test by experiencing these exercises ourselves and witness our own range of motion improve."

Your Teacher

Hi! I’m Yogi Aaron!

I look forward to welcoming you to my beachfront yoga retreat, Blue Osa, for a spiritually awakening experience.

I built Blue Osa to host groups in a safe, wild, and nurturing environment. I wanted to create a space where people could come and be immersed in a yogic lifestyle without all of the modern-day distractions. I wanted Blue Osa to help people come back home to themselves.

And since opening our doors, Blue Osa has provided just that to thousands of people.

Personally, I have 30+ years of yoga experience, have led countless yoga teacher training programs, and continue to embrace being a beginner at heart — constantly learning and expanding my own self-awareness and yogic knowledge.

I’ve designed Blue Osa’s Yoga Teacher Training to be a perfect blend of the ancient and spiritual practices of yoga (influenced by the Himalayan tradition) offered alongside modern-day, science-backed methods like AYAMA™ (Applied Yoga Anatomy + Muscle Activation) which is a revolutionary approach to yoga that eliminates pain by optimizing muscle function.

I can’t wait to have you join our Blue Osa family in a future training!

At Blue Osa we believe that nutritious, wholesome food is not only the foundation for a productive life but is also essential for a happy one. Food that nourishes our soul not only needs to be healthy, but it also needs to be delicious too!

We are devoted to serving the freshest ingredients possible that are delivered daily to our kitchen. Whether it’s pineapple from the Blue Osa property or squash from the farmers down the road, all produce supports the local economy.

This is truly a “farm-to-table” family-style dining experience. While attending our immersion, you’ll enjoy three meals/day and be able to purchase smoothies and elixirs from our Juice Bar as desired. Tea, coffee, filtered water, and fruit are always available too. Dietary restriction? No problem, just let our friendly kitchen staff know in advance!
